Operations
DynamoDB supports various operations to play with tables, items, and attributes.
Table operations
DynamoDB supports the create, update, and delete operations at the table level. It also sup-
ports the
UpdateTable
operation, which can be used to increase or decrease the provi-
sioned throughput. We have the
ListTables
operation to get the list of all available
tables associated with your account for a specific endpoint. The
DescribeTable
opera-
tion can be used to get detailed information about the given table.
Item operations
Item operations allows you to add, update, or delete an item from the given table. The
Up-
dateItem
operation allows us to add, update, or delete existing attributes from a given
item.
The Query and Scan operations
The
Query
and
Scan
operations are used to retrieve information from tables. The
Query
operation allows us to query the given table with provided hash key and range key. We can
also query tables for secondary indexes. The
Scan
operation reads all items from a given
table. More information on operations can be found in
